The Black Diamond Mercury 65 Pack is a good option. With the Black Diamond Mercury 65 Pack you are getting decent weight, lots of organization, great waist support and a solidly made pack. The one thing with this Black Diamond Mercury 65 Pack is the waist support. It rotates around, so if you are hiking and are going through some terrain like rocks, hills, etc. the Black Diamond Mercury 65 Pack moves with your movements, versus the pack moving in a solid way. It is quite different feeling, but in a good way. You will find plenty of storage mesh compartments throughout, and two outside water bottle holders. I travel with a saw and an axe and used the provided hiking pole holder for my axe and it worked great. This Black Diamond Mercury 65 Pack has lots of compression straps, so whatever you put in there you can compress it easily.
The one area I see for improvement is the zippers. The Black Diamond Mercury 65 Pack has waterproof zippers on it and they are a pain. Difficult to open, they get stuck at times and worst of all I have had some pop. Now I got them back on track with a simple zip and unzip, but they did pop. Could be the load I had in it and pushing limits, but these zippers need to be changed to challenge for a top notch backpack. On a smaller critique, the shoulder straps are narrow and could be enlarged to distribute the weight better across the shoulders. All in all, I do enjoy using the Black Diamond Mercury 65 Pack, but I am mindful of not going above 35 pounds. I have found that is the magic number. Getting much above that leads to shoulder strain. But around 35 pounds and this pack is killing it all day everyday. Also, bravo Black Diamond for using a mud color, similar to a dark coyote brown color. Many manufactures use bright colors, but people like me like just a simple brown or green. I am glad to see this type of color. Berz Rating: 83/100
